Model Card for qwen3-4b-mascarade-iot-lora

This model is a fine-tuned version of Qwen/Qwen3-4B-Instruct-2507. It has been trained using TRL.

Quick start

from transformers import pipeline

question = "If you had a time machine, but could only go to the past or the future once and never return, which would you choose and why?"
generator = pipeline("text-generation", model="Ailiance-fr/qwen3-4b-mascarade-iot-lora", device="cuda")
output = generator([{"role": "user", "content": question}], max_new_tokens=128, return_full_text=False)[0]
print(output["generated_text"])

Training procedure

This model was trained with SFT.

Bench results — iact-bench Phase 8 (Docker validators, 2026-05-11)

Functional eval via the iact-bench v0.2 Docker sandbox validators (no-network, read-only rootfs, uid 1000 dropped caps, --tmpfs /tmp:size=256m). Source LoRA: Ailiance-fr/qwen3-4b-mascarade-iot-lora. Eval samples drawn with seed=101 from Ailiance-fr/mascarade-iot-dataset.

Metric	Value
Validator	judge-only
Tmpfs cap	256m
Samples	10
Pass rate	0.0
Total validator wall-clock	0.0s

Pass = sandboxed compile/exec succeeds (exit_code=0). See iact-bench/configs/domain_validators.yaml for the exact toolchain invocation (arm-none-eabi-gcc / arduino-cli / freecadcmd depending on domain).

Upstream base model — official evaluations

These are the official scores for the unmodified base model Qwen/Qwen3-4B-Instruct-2507, reported by Alibaba Qwen team. They represent the floor of capability that this LoRA inherits before the hardware-domain fine-tune adapts behavior.

Reading these numbers alongside the Phase 6 bench above: the upstream scores measure general capability (knowledge, reasoning, coding, alignment). The Phase 6 deltas measure hardware-domain specialization (KiCad, SPICE, schematic extraction). A rank-16 LoRA adapter modifies less than 1% of base weights, so the upstream scores remain approximately the floor — this LoRA adds the Phase 6 deltas on top of these inherited capabilities.

This LoRA (tuned) — bench PENDING

Will include iact-bench Docker validators per domain + N3 5-axis kicad-cli. Production usage: compiled to Tower Ollama Modelfile, served via gateway alias ailiance-<domain> (kicad/spice/stm32/emc/embedded/platformio/freecad/dsp/iot/power).

Cross-domain forgetting check (Phase 9, 2026-05-11)

For each domain's eval set (seed=101, n samples held-out), compare this LoRA's Jaccard token-overlap vs the Qwen3-4B-Instruct-2507 baseline (no adapter) on the SAME prompts. Negative Δ = the LoRA degrades base behaviour on that domain.
